Storage Drum Assembly

Abstract

A storage drum assembly is described. The storage drum assembly is typically cylindrical, and comprises an outer wall portion, a top portion having a port or ports thereon, and a base having a generally conical sump portion with a frustum base. The storage drum assembly can also include an extended upper chime with a support lip, which enables attachments secured within the port or ports of the storage drum assembly to remain in place and protected from damage when multiple storage drums are stacked when not in use.

         6 . The storage drum assembly of  claim 5  wherein the bottom chime further includes a plurality of support ribs disposed on the outer wall portion of the bottom chime. 
     
     
         7 . The storage drum assembly of  claim 5  wherein the storage drum assembly further includes an upper chime extending upwardly and outwardly from the top portion, such that the circumference of the distal end of the upper chime is greater than the circumference of the upper chime proximate the top portion, the upper chime having an inner wall portion and an outer wall portion. 
     
     
         8 . The storage drum assembly of  claim 7  wherein the upper chime further includes a support lip directly coupled with the inner wall portion of the upper chime, the support lip extending out from the inner wall portion and inwardly towards the center of the top portion. 
     
     
         9 . The storage drum assembly of  claim 7  wherein the upper chime further includes a plurality of support ribs disposed on the outer wall portion of the upper chime. 
     
     
         10 . A first storage drum assembly of  claim 8  in combination with a second storage drum assembly of  claim 8 , wherein the distal end of a lower chime of the first storage drum assembly is removably coupled with a support lip of an upper chime of the second storage drum assembly. 
     
     
         11 . The storage drum assembly of  claim 1  further comprising a security tab, wherein the security tab is directly coupled to the top portion proximate the port. 
     
     
         12 . A storage drum assembly, comprising:
 a generally cylindrical outer wall portion having a first end and a second end defining an interior storage volume therebetween;   a top portion attached to the first end of the cylindrical outer wall;   a bottom sump portion attached to the second end of the cylindrical wall, the bottom sump portion having an oblique conical shape and a frustum base, wherein the frustum base is substantially parallel to the top portion;   a port operationally connected to the top portion;   an upper chime extending upwardly and outwardly from the top portion, the upper chime having an inner wall portion and an outer wall portion; and   a lower chime extending downwardly from the bottom sump portion.   
     
     
         13 . The storage drum assembly of  claim 12 , wherein the port is oriented directly above the frustum base. 
     
     
         14 . The storage drum assembly of  claim 12  wherein the port further includes a chemical mixer tool removably attached thereon, the chemical mixer tool having a mixer housing assembly, a mixer shaft, and an impeller assembly. 
     
     
         15 . The storage drum assembly of  claim 13  wherein the port further includes a pump assembly removably attached thereon, the pump assembly having a pump tube and a dip tube fitting, the dip tub fitting having a plurality of bellows extending downwardly to and contacting the frustum base. 
     
     
         16 . The storage drum assembly of  claim 12 , wherein the upper chime further includes a support lip directly coupled to the inner wall portion, the support lip extending out from the inner wall portion and inwardly towards the center of the top portion. 
     
     
         17 . A first storage drum assembly of  claim 16  in combination with a second storage drum assembly of  claim 16 , wherein the distal end of a lower chime of a first storage drum assembly is removably coupled with a support lip of an upper chime of a second storage drum assembly. 
     
     
         18 . The storage drum assembly of  claim 12  wherein the upper chime and the lower chime further include a plurality of support ribs disposed on the outer wall portion of the upper chime and the lower chime, the support ribs beings substantially vertically oriented. 
     
     
         19 . The storage drum assembly of  claim 12  further comprising a security tab, wherein the security tab is directly coupled to the top portion proximate the port. 
     
     
         20 . A storage drum assembly, comprising:
